6 Hard disk drive or solid-state drive
Depending on models, your computer might have a large-capacity, customer-upgradable hard disk drive
that can meet a variety of storage demands.
Some models are equipped with a solid-state drive for data storage, making your computer lighter, smaller,
and faster.
Note: The hidden service partition is the reason why there is less free space than expected on your hard
disk drive or solid-state drive. This reduction is more noticeable on the solid-state drive because of its
smaller capacity.
